SPIRAL FAN ASSEMBLY

摘要

PURPOSE: A spiral fan assembly is provided to reduce the size of a blowing fan system to which a spiral fan is installed by generating a great amount of wind having great wind pressure using a small spiral fan assembly. CONSTITUTION: A spiral fan assembly includes a spiral fan(10) and a cylindrical fan housing(20). The spiral fan(10) has a rotating shaft(11) coupled to a driving motor, a cylindrical hub(12) fixedly coupled to the rotating shaft(11), and a plurality of blades(13) formed at an outer peripheral portion of the cylindrical hub(12) in a spiral pattern. A swirl guide(21) is integrally formed with an inner portion of an extension part of the fan housing(20) in such a manner that the swirl guide(21) has an orbit identical to an orbit of the blade(13) of the spiral fan(10).
